“Have used 4 of the strips a expected to see an improvement. I have had my teeth whitened professionally 1 year ago so expected the strip to brighten them. Seen no improvement after 4 strips and having them on 1 hour at a time.”
“Easy yet effective, none of this use one gel, bite down on a mouth guard style thing that makes you dribble, these strips work well and I'll definitely be using them again”
